ICD-10 Code I75.0 – Atheroembolism of extremities (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I75.0 – Atheroembolism of extremities
What it is
I75.0 identifies atheroembolism affecting the arms or legs. It means cholesterol or atherosclerotic debris has traveled from a larger artery and blocked smaller vessels in an extremity.
Clinical signs
Typical findings include sudden pain, coldness, pallor, or reduced pulses in the affected limb. Skin changes, toe or finger discoloration, and signs of distal ischemia may also appear; clinical features vary, so refer to documentation.
When to use this code
Use this code when the provider documents atheroembolism, cholesterol emboli, or embolic occlusion of an extremity from atherosclerotic plaque. It may apply after vascular procedures or in patients with known atherosclerosis when the limb findings are attributed to plaque debris. Check documentation for the exact vessel and laterality if recorded.
Do not use for
Do not use it for routine peripheral arterial disease, thrombosis, or emboli from a cardiac source unless the record specifically states atheroembolism. If the cause is unclear, check documentation.
Coding tip
Assign I75.0 only when the note clearly links the extremity ischemia to atheroembolic disease, not just to general arterial insufficiency.
